DC fans upgrade system cooling
Third-generation high-capacity direct-current fan is designed to cool high-power electronic systems
In today's technological environment, electronic systems are subjected to extreme heat losses due to increased packing densities and clock frequencies, which will soon be in the high tens of gigahertz range. Rittal's new RiCool III flatpack fan is a third-generation high-capacity direct-current fan that has been designed specifically for these high power losses.

The air intake design of the fan system has a maximum capacity of 320m3/h (unimpeded airflow, RiCool II: 275m3/h) and 71mm H20 static pressure, which can dissipate high heat losses, such as those found in AdvancedTCA applications.
Requiring just 1U of installation space, RiCool III is integrated as standard in Rittal's AdvancedTCA shelves.
Air is drawn in vertically, diverted through 90 degrees and blown out to the rear.
During this process, an even air flow is drawn up over the hot boards, thereby cooling them effectively despite the very narrow spaces and high packing density of the individual plug-in boards.
Weighing just 1.70kg, the fan unit is installed in a sheet steel housing and is available as a 48V DC design (equivalent to 1.5A rated current consumption at 100%).
The noise level (unimpeded air flow) is a small 64dB at full load (at 70% speed: 59dB).
The fans can be configured to work redundantly, allowing two or more fans to work at reduced speed in normal operation mode, thus reducing the noise level.
In the event of a blower failing, the other fans adjust to full power and continue the cooling of the system. Request a free brochure from Rittal....
